PHP - Adding A Hash Of Options To A Function
This would seem like a simple question, but I can't seem to find the answer anywhere. Perhaps I'm asking it wrong.
What I'd like to do is add a hash of optional arguments for a function. For example, I might have a function that has two required arguments, and three optional arguments. The only way I know to design this function is to put the arguments in a specific order, and fill them out to the degree needed. So if the 5th argument needs to be called, but the 3rd and 4th don't, you'd still have to give them values. function example($arg1, $arg2, $arg3, $arg4, $arg5) Must be used by: example('red', 'horse', '', '', 'texas'); Is there anyway of designing a function to only use the specified arguments? example('red', 'horse', ['arg5: texas']); Similar TutorialsHi Guys, I wonder If I can call on this forums help once again. I am trying to add salt to my md5 password hash. However I think I am getting the syntax slightly wrong as it is not working properly. It works in the fact that when someone logs in and they have a 1 next to the member type it will direct them to the teachers page . However if no values are entered into the log in form and someone clicks log in it will still direct them to the students page when I thought it would direct them to log in failed. The code for the log in form is: Code: [Select] //Sanitize the POST values $login = clean($_POST['login']); $password = clean($_POST['password']); $salt = "salt"; $EncryptedPassword=md5($password, $salt); //Create query $qry="SELECT * FROM users WHERE username='$login' AND password='$EncryptedPassword'"; $result=mysql_query($qry); //Check whether the query was successful or not if($result) { if(mysql_num_rows($result) == 1) { //Login Successful session_regenerate_id(); $member = mysql_fetch_assoc($result); $_SESSION['SESS_MEMBER_ID'] = $member['id']; $_SESSION['SESS_FIRST_NAME'] = $member['FirstName']; $_SESSION['SESS_LAST_NAME'] = $member['LastName']; $_SESSION['SESS_LAST_NAME'] = $member['Member_Type']; session_write_close(); } //if the member has an id equal to 0 send them to the member page if($member['Member_Type'] == 0){ header("Location: Student-Page.php"); //if the member has an id equal to 1 send them to the admin page } elseif($member['Member_Type'] == 1){ header("Location: Teachers-Page.php"); } // regardless of the outcome, we need to exit, so it can be done once after both checks exit(); } else { //Login failed header("location: login-failed.php"); exit(); } In case you need it the code for the registration form where the password is originally salted upon creation is: Code: [Select] <?php //Start session session_start(); //Include database connection details require_once('config.php'); //Connect to mysql server $link = mysql_connect(DB_HOST, DB_USER ,DB_PASSWORD); if(!$link) { die('Failed to connect to server: ' . mysql_error()); } //Select database $db = mysql_select_db(DB_DATABASE); if(!$db) { die("Unable to select database"); } //Function to sanitize values received from the form. Prevents SQL injection function clean($str) { $str = @trim($str); if(get_magic_quotes_gpc()) { $str = stripslashes($str); } return mysql_real_escape_string($str); } //Sanitize the POST values $username = clean($_POST['username']); $FirstName = clean($_POST['FirstName']); $LastName = clean($_POST['LastName']); $Member_Type = clean($_POST['Member_Type']); $password = clean($_POST['password']); $Cpassword = clean($_POST['Cpassword']); $salt = "salt"; $EncryptedPassword = md5($password,$salt); //Check for duplicate login ID if($username != '') { $qry = "SELECT * FROM users WHERE username='$username'"; $result = mysql_query($qry); if($result) { if(mysql_num_rows($result) > 0) { } @mysql_free_result($result); } else { //die("query failed"); } } //Create INSERT query $qry = "INSERT INTO users(username, password, FirstName, LastName, Member_Type) VALUES('$username','$EncryptedPassword','$FirstName','$LastName','$Member_Type')"; $result = @mysql_query($qry); //Check whether the query was successful or not if($result) { header("location: register-success.php"); exit(); }else { die("Query Failed"); } ?> If someone could take a look and point me in the right direction. Also if there are any other mistakes let me know I would be very grateful. Thanks in advance. Edd Specifically for hashing a password to be stored in a database. I know SHA1 and MD5 are essentially considered broken. I've been using MD5 with a salt value on all my projects but I'm starting a new project and wondering if there's a stronger algorithm I should be using? please help me in php i want that when a user clicks on add click a new box will be appeared for question consider user is doing work with questions and options he first gives a question after it he clicks on ADD button so a input box will appear den he clicks again to ADD button den aggain new box appears at last he clicks save then they would be inserted into database reply mee.. please Hi im having some trouble when i try to add values to an array from a function. The added value will not stay saved. fun1 will display both firstname and surname but when i call fun2 after calling fun1 i just get the firstname. I would like to have it so the array is updated and stays updated untill it is cleared or over written. Any help with this would be greatly appreciated. i am using codeigniter if that makes any difference. Thanks <?php class Test extends Controller { var $data1 = array( 'firstname' => 'craig' ); function fun1() { global $data1; $this->data1['surname'] = 'brute'; echo "<pre>"; print_r($this->data1); } function fun2() { global $data1; echo "<pre>"; print_r($this->data1); } } Hi all. I try to adding checkbox when I call my function, my Class code is Code: [Select] class SQLconn{ function fetchData($table_name, $argument, $linebreak, $end_linebreak){ $result = mysql_query("select * from $table_name where status='$argument'"); while($row=mysql_fetch_row($result)){ echo $linebreak.$row[1]."<input type='checkbox' name='option' id='checkbox' value=$row[0] />".$end_linebreak; //$row[0] is 'job_id' from database } } } and my view code is like this Code: [Select] <?php $connect = new SQLconn(config()); $connect->connectDB(); $connect->fetchData("todo", "Undone", "<li>", "</li>"); //this is where the problem is $connect->closeConn(); ?> With that code I succesfully achieve my goal to add checkbox with right 'job_id' value but this is a workaround and not good because if I code it this way my function will be broken if use it somewhere else. My question is, how can I fix my code so I can add checkbox to view page but I can keep my function clean? Really need opinion about this?? I cant figure out how to add $recieved into this needs to take place of time hope someone knows how to do this what im doing is adding in the UNIX time i want to offset Code: [Select] <?php $offset = date('m/d/Y/H:i:s', time()+$send1['time_offset']); ?> I made a function which displays the left and right children of the root. However i need to add serial numbers to them. Due to Recursive functions i'm not quite able to to do so . Can someone please help me? Code: [Select] function side_display($root) { $sql = "SELECT lchild,rchild FROM tree WHERE parent='".$root."'"; $sqlexec = mysql_query($sql); $array = mysql_fetch_array($sqlexec); if(!empty($array['lchild']) && $array['lchild'] != '0') { echo "<tr>"; echo "<td>".($array['lchild'])."</td>"; $get = "SELECT * FROM member WHERE member_id='".$array['lchild']."'"; $execget = mysql_query($get); $getarray = mysql_fetch_array($execget); echo "<td>".$getarray['fname']." ".$getarray['lname']."</td>"; echo "<td>".$getarray['id_sponsor']."</td>" ; echo "<td>Left</td>"; echo "<td>".$getarray['doj']."</td>" ; echo "</tr>"; side_display($array['lchild']); } if(!empty($array['rchild']) && $array['rchild'] != '0') { echo "<tr>"; echo "<td>".($array['rchild'])."</td>"; $get = "SELECT * FROM member WHERE member_id='".$array['rchild']."'"; $execget = mysql_query($get); $getarray = mysql_fetch_array($execget); echo "<td>".$getarray['fname']." ".$getarray['lname']."</td>"; echo "<td>".$getarray['id_sponsor']."</td>" ; echo "<td>Right</td>"; echo "<td>".$getarray['doj']."</td>" ; echo "</tr>"; side_display($array['rchild']); } } Hi,
I am using fancybox on my site and the function I am using to display the title and data-caption is this.
$(document).ready(function() {
$('.fancybox').fancybox({
beforeShow : function(){
this.title = this.title +"<br>" + $(this.element).data("caption");
}
});
}); // ready
I would like to change this so that I can add a hypertext link.
Here is what a sample of the HTML looks like:
<img src="img/portfolio/GSI_web.png" height="194" width="400" alt="Globalsoftwareinc.com" />
<h4>www.globalsoftwareinc.com</h4>
<div class="portfolio-desc align-center">
<div class="folio-info">
<h5><a title="globalsoftwareinc.com" href="#" title="www.globalsoftwareinc.com">Globalsoftwareinc.com</a></h5>
<a title="Global Software Inc. website" href="img/portfolio/GSI_web_large.png" class="fancybox" data-caption="I was the interactive web designer at Global Software, Inc. and assisted in the re-design and development of Global Software, Inc. in Drupal<br>www.globalsoftwareinc.com"><i class="fa fa-plus fa-2x"></i></a>
</div>
</div>
</div>
</article>
so for example I would want to make www.globalsoftwareinc a hyperlink and that isn't do-able currently. It breaks the code.
thanks in advance!
The web application should allow the user to view the items in a catalogue, add items to a shopping cart, remove items from the shopping cart, and to view the contents of the shopping cart. Hey guys. Right ill try explain as best i can. Basicly we were told to write a php script that can view a shopping cart. The items in the catalogue should be stored as an array of objects. (The next assignment will require you to store this list of objects in a database). There should also be pages to allow the user to add, edit and delete items in the catalogue. Thats taken from a brief.Ive spent the most of the week getting it to view a catalog and now it can add items.view the cart its added them to and remove them from the cart and return. What im having trouble with is making the add function for the the other users or admin* to add/edit/delete.i reckoned adding and deleting wouldnt be so bad considering ive alrready done so.But im kinda stumped on how to do it.i think what the brief wanted was a seprate product add that would actully let u add another product to the cart list on the same page and then u can add that to the shopping basket etc. Yea real stumped.if only it was through sql it would be so much handier. ill post the code below.if anyone can help at all in the slightest id be so grateful.Thank you. Guys, Having a major headache here. I need to send an enquiry using jquery and php. The user can only send an enquiry if they are logged in - so it's a one click process. On the click (which is an <a> tag) the user's data is retrieved from the database and sent to the company they are enquiring about. When the link is clicked, a jquery popup is shown to notify the user that the enquiry has been sent. This all works. However, currently the enquiry is sent when the page loads and this is what I'm having trouble with. Code: [Select] <a href="#e" onclick="openinfobox('Enquiry Sent', 1)" class="enq"></a>What I want to do is say if the URL contains #e, then send the enquiry, otherwise do nothing. I understand that the # portion of the url cannot be referenced by PHP. How on earth can I run php process to say only run this php process if there is a # in the url? Is a hash array the same thing as an associative array? My PHP books make no reference to this, yet I have seen the term referred to. Thanks. Are there any PHP hashes that are extremely secure and that CANNOT be reverse-engineered?
I have a section on my website where the url points to www.example.com/some_page#some_element #some_element is used by javascript to load the element in question into the parent element. However i need pagination done on this loaded element. How should i go about it? would it work? obv i cant use www.example.com/some_page#some_element/page/2. Any tips or advice? Trying to echo a string that contains a hash symbol. Instead of getting a hash symbol, I get %29. The code I am using is pretty basic -->$idx="#" . $idxA;<--, but as stated, when I echo $idx, it comes out as %29. (All of this is part of a form, get, attempting to pass a bookmark to the receiving program. Thoughts? When a User changes his/her Email Address, should I generate a new Salt and Hash? (I am re-using the code I used for a Password Reset, and during that I generated a new Salt and Hash for security. I guess it can't hurt...) Thanks, Debbie Hello, I created a system where emails get encrypted with a random key that gets stored in a database, what are the odds of the Hashes Colliding? Part of the code: function genRandomString($num) { $length = $num; $characters = '0123456789abcdefghijklmnopqrstuvwxyz'; $string = ""; for ($p = 0; $p < $length; $p++) { $string .= $characters[mt_rand(0, strlen($characters))]; } return $string; } $Key=genRandomString(10); $email_s=hash_hmac('ripemd160', $email, $Key); Thankyou, GB. Hi SMF forum use semi-colom in url for example http://www.phpfreaks.com/forums/profile/?area=showposts;u=71740 after showposts there is semi-colon. Sometimes use hash(#) how can i do this with superglobal $_GET??? Im using SMF forum im trying to connect (my software C#) and grand access from forum DB this is a hash from SMF sha1(strtolower($membername) . $password); Code: [Select] <?php include("config.php"); $user = "-1"; if (isset($_GET['user'])) { $user = $_GET['user']; } $pass = "-1"; if (isset($_GET['pass'])) { $pass = $_GET['pass']; } $ip = $_SERVER['REMOTE_ADDR']; $sql = "select id_member,count from smf_members where real_name='$user' and passwd=MD5('$pass')"; $results = mysql_query($sql, $con); $values = mysql_fetch_assoc($results); $user_id = $values['id_member']; $login=$values['count']; ?> MD5 working fine but how to use SMF hash to login? Hi,
I am trying to get this script to execute as an administrator of an online system. If a user has forgotten their password, I enter their username and enter a new password which they can update later. I am not sure why this is not updating the password for the username entered?
<?php
// Initialize the session
session_start();
// Check if the user is logged in, if not then redirect to login page
if(!isset($_SESSION["loggedin"]) || $_SESSION["loggedin"] !== true){
header("location: login.php");
exit;
}
// Include config file
require_once "config.php";
// Define variables and initialize with empty values
$new_password = $confirm_password = "";
$new_password_err = $confirm_password_err = "";
// Processing form data when form is submitted
if($_SERVER["REQUEST_METHOD"] == "POST"){
// Validate new password
if(empty(trim($_POST["new_password"]))){
$new_password_err = "Please enter the new password.";
} elseif(strlen(trim($_POST["new_password"])) < 6){
$new_password_err = "Password must have atleast 6 characters.";
} else{
$new_password = trim($_POST["new_password"]);
}
// Validate confirm password
if(empty(trim($_POST["confirm_password"]))){
$confirm_password_err = "Please confirm the password.";
} else{
$confirm_password = trim($_POST["confirm_password"]);
if(empty($new_password_err) && ($new_password != $confirm_password)){
$confirm_password_err = "Password did not match.";
}
}
// Check input errors before updating the database
if(empty($new_password_err) && empty($confirm_password_err)){
// Prepare an update statement
$sql = "UPDATE User_Accounts_ SET password = ? WHERE username = ?";
if($stmt = mysqli_prepare($link, $sql)){
// Bind variables to the prepared statement as parameters
mysqli_stmt_bind_param($stmt, "ss", $param_password, $username);
// Set parameters
$param_password = password_hash($new_password, PASSWORD_DEFAULT);
$username = $_POST['username'];
// Attempt to execute the prepared statement
if(mysqli_stmt_execute($stmt)){
// Password updated successfully. Destroy the session, and redirect to login page
session_destroy();
header("location: login.php");
exit();
} else{
echo "Oops! Something went wrong. Please try again later.";
}
// Close statement
mysqli_stmt_close($stmt);
}
}
// Close connection
mysqli_close($link);
}

What is the difference between the hash algo "tiger192,3" and "tiger192,4"? I ran fsum/HashCalc to get a TIGER hash from a string and it is different with either "tiger192,3" or "tiger192,4". I also tried using the hash as hex string input to rehash 3 or 4 times, but still cannot get an equivalent to that of "tiger192,3" or "tiger192,4"... |
